Great game, couple of flaws though
Overall, a surprisingly addictive game, reminds me of the sliding ice levels on Pokemon games for the GBA ;].
Pros:
Liked the graphics, simple and effective
The 'Music: on/off' button at the very start was much appreciated :)
The breakable blocks added an interesting dimension to things
One major con:
I really did not like the coloured key system from level 25 onwards or whenever it was. Made it too complex and unpredictable - too open to whimsy rather than the logical steps of rotating the board to place the blob where it was meant to be. If you could see an outline of the blocks that the keys made that might be better.
Would've been a 9 or a 10 without that.
